Characterization of AuNDs.
(a) The optical absorption peaked at 808 nm. Inset TEM image accurately shows the aspect ratio of rod-shaped AuNRs. (b) cTEM images of NDs and AuNDs. (c) Size distributions of NDs and AuNDs. (d) Temporal temperature profiles for water, NDs and AuNDs during exposure to continuous-wave laser radiation.
